Cardio Workout: Get More From Your Cardio

Strip
away abdominal fat by switching around your cardio routine so you run
hard early.

In a study published in the European Journal of Applied Physiology, eight men ran for 30 minutes on two separate days. In the first session, the men ran at a relatively high intensity  80 percent of their maximum heart rate  for 15 minutes, then slowed to 60 percent for the final 15 minutes. In the other session, they ran the slower part first. The men burned five to 10 percent more fat when they ran faster at the start of the workout.
